JAMES H` KEIDERLING, OF BOUNDBROOK, NEW JERSEY.

-BOGIE-TRUCK.

T0 all whom it may concern.'

Beit known that I, JAMES H. KEIDERLING, a citizen of the United States,residing at Boundbrook, in the county of Somerset and State of NewJersey, have invented an Improvement in Bogie-Trucks, of which thefollowing is a specification.

This invention relates to bogie trucks designed especially for use inmachine shops, railway rail shops and like places for moving heavybodies to points in the shops which the traveling cranes cannot reach,and has for its objects to produce a comparatively simple, inexpensivedevice of this character which will possess the requisite strength anddurability, one wherein the truck may be readily mani ulated fordepositing the load carried there y into a certain predeterminedposition, and one in which the upper frame or turn table will besusceptible of free movement.

With these and other objects in view, the

-invention comprises the novel features of construction and combinationof parts more fully hereinafter described.

Figure 1 is a reverse plan view of a truck embodying the invention,parts of the truck being shown in dotted lines. Fig. 2 is a sideelevation of the device. Fig. 3 is a sectional view taken centrally andlongitudinally through the' truck on the line 3-3, Fig. 1. Fig. 4 is asideelevation of one of the side rails of the frame. Fig. 5 is a similarview of one of the end bars of the frame. Fig. 6 is a view in elevationof the swivel plate lock pin. Fig. 7 is a side elevation of one of theroller shafts.

Referring to the drawings, it will be seen that the device embodies alower frame comprising side rails 1 and end bars or members 2 havingterminal tenons 3 adapted to'iit in suitable mortises or perforations 4formed in the rails 1 at points near their ends, there being attached tothe lower faces of the rails 1 bearing members or journals 5 providedwith suitable bearing openin s to receive the circular portions or spindes 6 formed on the ends of squared shafts or axles 7 extended centrallyand longitudinally through the rollers 8 on which the truck is mountedfor travel.

Attached to the upper face of the lower frame is a circular swivel plate9 provided with a central openin 10 and with an annular raceway 11 formeto receive anti-friction members or balls 12 disposed between saidSpecification of Letters Patent.

plate and an upper swivel plate 13 corresponding to the plate 9 andhavinga central opening 14 and on its lower face an annular raceway 15which conjointly with the raceway 11 accommodates the anti-frictionballs.

Fixed upon the upper face of the upperV swivel plate 13 is an uppersupporting frame similar in form to the lower frame and comprising siderails 16 and end bar 17 provided with terminal tenons 18 formed to iittransverse openings or sockets 1'9 provided in the rail 16, the bars 2and 17 being iixedly attached to their respective side rails by means ofvertical coupling pins 20 entered through alined openings formed in therails and in the tenons formed on the ends of the bars.

-The plates 9 and 13 which constitute a turn table are pivotallyconnected for rotation one upon the other by means of a vertical pintleor bolt 21 entered through the o enings 10 and 14 which are arranged ina inement, the plates being attached to their respective frames by meansof bolts 22.

In practice, the load to be transported by the truck is arranged uponthe upper frame and the truck moved from place to place during whichoperation it travels upon the rollers 8 as will be readily understood.After reaching the point of destination the load carried upon the truckis deposited in a manner which will be apparent, it being understood,however, that the upper frame may, owing to the interposed turn table,be readily shifted upon the lower frame in order that the articles onthe truck may be arranged in a certain predetermined osition; forexample, if the truck be use for transporting railway rails the upperframe may be shifted to the requisite position in order that the railsmay be properly iled in alinement. During the movements o the upperframe the anti-friction balls 12 permit of the upper plate 13 turningfreely upon the lower plate 9.

It is to be noted that the device herein described while of simpleconstruction will be exceedingly strong and durable, thereby renderingit effective in the handling of very heavy loads, such as will be metwith in locomotive factories, railway rail shops, and machine shops, andfurthermore, that Vparts of the device which may become defectivethrough wear or other causes may be conveniently renewed ascircumstances require.

What I claim is:

1. A truck of the type described comprising a lower frame, a swivelplate attached thereto and provided with an annular raceway, an upperframe having a swivel plate attached therebeneath and provided with anannular raoeway opposed to the firstnamed raceway, anti-friction ballsarranged between said plates within the raceways, bearings attachedbeneath the lower frame, rollers on which the truck is arranged fortravel, and axles extended longitudinally through said rollers andhaving terminal journals disposed for rotation in said bearings.

2. A truck of the type described comprising an upper and a lower frame,each consisting of side bars provided with sockets, and end bars havingtenons fitted in said sockets, coupling pins extended through the sidebars and tenons, a turn table interposed between the frames andcomprising a pair of' Witnesses:
